The National Rare Blood Association is suspected of laundering money to terrorist groups. When Private Investigator Mark Matthews and FBI Agent Susan Harrington collect evidence against the NRBA, they become willing combatants in the "War on Terror."

John Portman, Director of Security for the NRBA is equally intent on avoiding detection. When he traces Mark's and Susan's probe into the NRBA's computer, Agent Harrington soon finds herself the victim of a savage abduction. Mark is called in for his highly developed techniques for locating missing persons in the hopes of finding her.

The recovery of Susan only fuels the romance building between the two law enforcers. However, unknown to both, Portman's assistant Mel Tarkington is hell bent on revenge against Susan, waiting for the right opportunity to penetrate the shield of protection that the FBI erected around her.
